SealVow vs OneSpan

OneSpan secures bank transactions. SealVow secures legal ones.

OneSpan built its reputation securing banking transactions with identity verification and e-signatures. For financial institutions, it's a natural fit. For law firms, it's an enterprise platform designed for a different industry — with the pricing and complexity to match.

Why teams switch from OneSpan

Your firm's name, not ours

Signing emails come from your domain. The signing page carries your firm's branding. Your clients see a professional experience that feels like an extension of your practice, not a third-party tool.

Clients sign in 30 seconds

No account creation. No app download. No 'verify your email' interruption. Your client clicks a link, reviews the document, signs it, done. Completion rates above 90% because you removed every barrier.

SRA-ready audit trail

Every signature records IP address, browser, timestamp, and explicit consent text. Full chain of custody from upload to completion. Exportable audit certificates that satisfy regulatory enquiries.

Document integrity you can prove

Every document is SHA-256 hashed at upload. The hash is recorded immutably before signing begins. If anyone questions whether the document was altered, you have cryptographic proof.

The bottom line

OneSpan is excellent at what it does — securing high-value financial transactions with identity verification. But law firms need signing that's built for legal workflows, not banking ones. SealVow gives you the audit trail depth without the enterprise overhead.
